Title:
SEPARATION MEMBRANE SHEET, SEPARATION MEMBRANE ELEMENT, SEPARATION MEMBRANE MODULE, AND SEPARATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/117361
Kind Code:
A1
Abstract:
This separation membrane sheet, through which a specific gas component is selectively pass, has: a first porous layer; a separation functional layer laminated on the first porous layer; and a second porous layer laminated on the opposite side to the separation functional layer of the first porous layer. The separation functional layer is a non-porous resin composition layer, and the first porous layer and the second porous layer are porous layers different from each other. The average pore diameter of the first porous layer is 0.005-1 μm, and the thickness of the first porous layer is 5-150 μm. The scale deviation of the second porous layer is 0.6 g/m2 or less.
